论文摘要
我们在12。5年的Fermi-Lat数据中搜索了114个银河高质量X射线二进制文件的伽马射线排放，其中包括4个经过良好研究的分类源，并与10年的点源目录结合使用。如果伽马射线过量与X射线二进制相吻合，则进行了进一步的研究，以确定这种过量是否是二进制系统本身内物理过程的产物。我们确定与20个高质量X射线二进制文件一致的伽马射线过剩，那里很少或没有伽马射线排放的证据。但是，我们发现其中许多是由源混乱或伽玛射线背景引起的假阳性。尽管如此，针对多个新系统的暂定但有希望的伽马射线发射指标，特别是包括1A 0535+262，RX J2030.5+4751和SAX J1324.4-6200。
We search for gamma-ray emission from 114 Galactic high mass X-ray binaries, including 4 well studied catalogued sources, in 12.5 years of Fermi-LAT data in conjunction with the 10-year point source catalogue. Where a gamma-ray excess appears to be spatially coincident with an X-ray binary, further investigation is performed to ascertain whether this excess is the product of physical processes within the binary system itself. We identify gamma-ray excesses coincident with 20 high mass X-ray binaries where there is little or no prior evidence for gamma-ray emission. However, we find that many of these are false positives caused by source confusion or the gamma-ray background. Nonetheless, tentative but promising indicators of gamma-ray emission are identified for several new systems, notably including 1A 0535+262, RX J2030.5+4751 and SAX J1324.4-6200.
